Life is random. So are career choices. If it wasn't for a tropical storm named Agnes in 1972 I might have a real job right now. The storm stalled over my boyhood home in Pennsylvania, flooding our lower level, leaving my mother distraught. It was traumatizing.
* We continue to watch two tropical depressions this morning that look to impact parts of the U.S. over the next few days.
* Tropical Depression Eight, off the Carolina coast, will make a quick approach to the Carolinas later this week before being pushing back out into the Atlantic by a cold front. A Tropical Storm Watch has been issued from Cape Lookout to Oregon Inlet, NC.
* Tropical Depression Nine, in the Gulf of Mexico, will attempt to strengthen into a tropical storm over the next 24-48 hours, eventually swinging to the northeast and making a likely landfall in Florida.
* We are also keeping an eye on Hurricanes Lester and Madeline in the Pacific as they could impact the Hawaiian Islands late this week.

Summary: We continue to watch two systems in the Atlantic that could have an impact on the mainland of the U.S. as we head into the middle of this week. The first, Tropical Depression Eight, looks to brush the Outer Banks with strong winds and higher surf before being pushed back into the Atlantic. The second, and of greater concern, is Tropical Depression Nine, which could make landfall Thursday in Florida as a Tropical Storm. We will also be keeping an eye on two hurricanes – Madeline and Lester – that could approach Hawaii late this week.

Historic August Flood Caused by "Seemingly Innocuous" Disturbance, Louisiana's Climatologist Says. Here's an excerpt of a story at Baton Rouge Business Report that caught my eye: "...To be classified as a 1,000-year flood event, 21.3 inches of rainfall is required, Keim says. Some areas in the Baton Rouge area far exceeded that. Watson received a whopping 31.39 inches of rain. The Brownfields area saw 26.8 inches, and Denham Springs had 25.5 inches. Keim says nine recording stations exceeded the 1,000-year flood mark. It was the heaviest rainfall on record in the history of Louisiana. “Not only did we beat the record—we crushed it,” Keim says. A flood of this magnitude originating from a small tropical wave is very unusual, Keim says, but the high moisture in the atmosphere from the Gulf of Mexico and the high humidity enabled the system. It was able to take the moisture in the atmosphere and bring it to the ground, he says..."
Map credit: "Projections of stagnant air days under continued heat-trapping gas emissions and warming show future increases in the number of these days in both the growing western U.S. and the highly populated eastern areas. As global temperatures warm, the difference between temperatures at the poles and the equator are decreasing, and this is projected to influence the jet stream, bringing an overall decrease in storm tracks through the midlatitudes (including areas over the continental U.S.) and decreasing windiness. The result could be longer spans of stagnant air hanging over U.S. regions."
Iowa Utilities Board Approves Huge Wind Energy Project. Some staggering statistics and projects for renewables south of the border, courtesy of AP and KCRG.com: "The Iowa Utilities Board has approved a wind turbine operation it says will be the nation's largest wind energy project. Des Moines-based MidAmerican Energy is behind the planned $3.6 billion wind turbine operation that will generate up to 2,000 megawatts of electricity. MidAmerican Energy said that is enough 800,000 homes and the project will see 85 percent of the company's Iowa customer needs met through wind energy by 2020..."

Grasping Climate Change. Phil Plait explains why it's so hard for our brains to grasp at Slate: "And that is the true evil of climate change. It’s slow, and patient. It’s everywhere, but takes its time. It operates every day, but its effects don’t manifest for decades. Weather changes every day, every hour, and that noise washes out the signal of climate change. Unless, that is, we too are patient, and keep our eyes on the long view. When we do, we see the trend, not the bumps and wiggles. This short, one-minute video frames it the best way I have ever seen: as a person walking a dog: If we watch the trend, and not the wiggles, we see the impact of humanity on our planet. The temperature trend is actually quite clear now. And that trend is up..." (File photo: Santiago Borja).
